I enjoy clever business cards but I am not certain that they are always the best way to communicate or simply transfer your contact information. However I do think that people find them delightful and they can make a strong initial impression on the recipient. Since they are difficult to keep because they are often odd shaped or odd sized I believe that sadly many are soon discarded after the novelty value has worn off.
Here is a link to an assortment of clever business cards recently shared with me. Enjoy!
